Lesson 1: Phases of the Cell Cycle

Cell Division

  • Viruses require a host cell to divide.
  • Cells that have the ability to divide have a cell cycle.
  • Let's look at the eukaryotic cell cycle

 

The cycle has two phases

  • During interphase, the cell grows and DNA is replicated.
  • During the mitotic phase, the replicated DNA and cytoplasmic contents are separated and the cell divides.

There are two types of cell division in eukaryotes.
